2012~2016年杭州市富阳区蔬菜中农药残留 监测及分析

目的 了解我国南方地区蔬菜中农药残留情况,为制定蔬菜农药残留限量标准和加强监督农业安全生产提供依据。 方法 2012—2016年采集杭州市富阳区农贸市场和生产基地等销售的新鲜蔬菜共671份,按照NY/T 761-2008 《蔬菜和水果中有机磷、有机氯、拟除虫菊酯和氨基甲酸酯类农药多残留的测定》方法对30种常用农药的残留量进行检测,并以GB 2763-2014 《食品安全国家标准 食品中农药最大残留限量》作为判定标准。 结果 对671份蔬菜样品进行农药检测和数据分析显示,检出农药阳性样品146份,检出率为21.8%,超限量样品为15份,占2.2%。共检测出农药种类20种,频次182。其中,叶菜类蔬菜中农药检出率最高,达30.3%；瓜类蔬菜中农药检出率仅为4.0%。 结论 部分蔬菜中农药残留较高,甚至超出国家标准,农业安全生产监督仍需加强。国家标准中缺乏部分农药在特定蔬菜中的限量标准要求,急需完善。

Monitoring and analysis of pesticide residues in vegetables in Fuyang district of Hangzhou city from 2012 to 2016

Objective To investigate the pesticide residues in vegetables in Southern China, as well as to provide the basis for revising the limitation standard and strengthening the supervision of agriculture production safety. Methods From 2012 to 2016, 671 fresh vegetable samples were collected from traditional markets and farms in Fuyang District of Hangzhou City. 30 pesticides were detected in these samples based on NY/T 761-2008, and the results were evaluated according to the limitation standards in GB 2763-2014. Results Among these samples, 146 samples with pesticide residue were detected, and the positive detection rate was 21.8%. The residue level in 15 samples was higher than the limitation, and the substandard rate was 2.2%. 20 kinds of pesticides were detected with a frequency of 182. The detection rate of pesticide residue in leaf vegetables was 30.3%, the highest. On the other hand, the detection rate in gourd vegetables was only 4.0%. Conclusion The pesticide residue level was high in certain kinds of vegetables, and some even exceeded the national standard limitation. So the safety supervision of agriculture production should be enhanced. The limitation standards of kinds of pesticides in some vegetables are lacked and should be complemented as soon as possible.
